Is Cardiac Evaluation Before Surgery a Mistake?

Do people with no cardiac symptoms really need coronary artery angiography before surgery? It often results in cardiac interventions such as stents.

Many people anticipating some type of operation other than one on their hearts are sent for cardiac evaluation with coronary artery angiography before surgery.  Surgeons want to make sure that their patients are not at high risk of having a heart attack or stroke in the middle of the procedure. But it is not clear whether this kind of evaluation is helpful, or whether it might result in unnecessary interventions for some patients.

Many People Are Referred for Cardiac Interventions Before Surgery:

A new study of nearly 200,000 people shows that, although most of these individuals did not have cardiac symptoms, nearly half were referred for a stent or bypass graft before surgery. More than half had been taking medicine for angina prior to the evaluation.

This study confirms that many patients who need some type of surgery may have some blockage in their coronary arteries. The majority of these individuals were overweight or obese and they were, for the most part, older men.

Cardiac Stents and Bypass Offer No Benefit for Asymptomatic People Before Surgery:

The conclusions note that randomized controlled trials have shown no benefit in outcomes for asymptomatic patients undergoing cardiac intervention before surgery. Complications from balloon angioplasty, stenting or coronary bypass operations are uncommon but not unheard of. About 0.05 percent of those undergoing catheterization died as a result of that procedure. The journal, JAMA Internal Medicine, published this research under its special “Less Is More” rubric.

    Any good car mechanic will tell you, “Don’t fix what ain’t broke.” About time the word reached the medical folks.

    A heart catheterization is not necessary. You can die more from them than a heart attack, I know. I had one 15 yrs. ago and never will I forget the nightmare of this. If I didn’t have a heart attack from that I never will. They messed me up at that hospital doing that process. Outcome of that was internal bleeding, was bruised badly, and couldn’t even stand up straight or lay down in the bed flat at night for 8 weeks. Don’t know what they did to me but it went all wrong. Think I was an experiment for practicing students too and it almost cost me my life. And I was told this was a same day procedure. ha ha what a joke. Wonder just how many people have died from these and its been brushed off as a heart attack, like it was the patients fault. All I can say these things are more dangerous than anyone will ever know.
